To all whom t may concern:

Be it known that LCHARLES J. KINTNER, a citizen of the United States, and resident of New York, borough of Manhattan, county and State of New York, have'made a new and useful Invention in Syringes Adapted to Use Liquids Under Pressure, of which the following is a specification.

My invention is directed particularly to novel means for utilizing liquids with syringes upon t-he siphon principle, and it has for its objects, first, to effect such result without the use of well known types of fountain syringe bags. Second, to effect such result with either stationary or portable wash-basins in toilet rooms and elsewhere. Third to provide a fountain syringe which may be used with any open top vessel, such as a wash-basin, pitcher, pail or the like and without the aid of a cutoff, such as is now used in connection with fountain syringes provided with flexible tubes and portable supply bags. Fourth, to provide a fountain syringe with a novel type of cut-off consti- Y tuting a part of the nozzle or the connector to the flexible tube. Fifth, to effect -a relatively large flow and corresponding increased pressure froin syringe tubes by the use of the means hereinafter described and claimed.

I have devised a very simple type of fountain syringe, the same consisting of a flexible tube only, and a nozzle and means for holding the induction end of the tube in a vessel containing the water to be used, the diameter of the tube being relatively large as compared with the liquid conveying capacity of the eduction hole or holes at the end of the nozzle, whereby relatively much greater pressure and hence better results are had. If the tube be fullyfilled with water and then closed, either with the thumb and finger of the user, or with a cut-off at 'a point near the nozzle, the same may be used by leaving or inserting the induction end thereof in the vessel and then'allowing the water to flow on the principle of a siphon, the weight of the water in the -eduction end being suliicient to give to the water being utilized atthe mouth of the nozzle the pressure due to the entire column of water from the point where the nozzle is used tothe bend of the tube where it leaves the vessel, so that by using a tube and a nozzle of relatively large diameter I am enabled to obtain sufficient head or flow from an ordinary stationary washbasin to give better results than is possible with the existing type of bag fountain syringe, when the bag is located several feet from the floor.

For a full and clear understanding of the invention, such as will enable others skilled in the art to construct and use the same, reference is had to the accompanying drawings, in which,

Figure l is a part sectional, part side elevational view illustrating my complete invhention in all of its details; and Fig. 2 is a similar but enlarge sectional view through that part of the invention, in the nature of a metal containing cup,l which constitutes also the weight or means of holding the induction end of the syringe tube beneath the water in the bowl, basin, or other receptacle with which the syringe is used, said tube being shown in section as in folded or coiled position with the nozzle and connect-or also inclosed therein and the cup covered with a lid or cap. Fig. 3 is an enlarged part Sectio-nal, part side elevational View of my novel form of connector as combined with a detachable nozzle and with the induction end of a syringe tube Referring now to the drawings in detail A represents a liquid containing vessel, such as a basin filled with water; B a flexible tube preferably of soft rubber, and C a weight of cup-like shape or construction and having a base-fiange D and an internally located tubular neck N, the base flange being provided with a plurality of openings K, all arranged so that water may pass from the vessel A upward through the tube B.

E is the nozzle and F a screw-threaded curvilinear connector secured to the nozzle, said connector being provided with the usual neck for securing it to the tube B, as shown.

G is a cut-off of set screw form, secured in a screwthreaded opening in the axis of the connector F and cone-shaped at its inner end so as to'be seated, when secured in the manner shown,'in a coned seat, thereby acting as an absolute cut-oft' for the flow of the water when desired, its operation being obvious. This type of cut-oflzI has an especial utility in that it, together with the nozzle E, constitute in effect a combined curved nozzle in which the axis of the cut-off G lies in the axis of that part of the combined nozzle which is connected directly to the syringe tube B, and the peculiar curved formation of the combined parts renders it easy of use and the cut-off in convenient access to the fingers of the user. This cutoff may take any angular relation to the nozzle, but is located preferably in the axis of this part, as shown. This combined nozzle and cut-off is not unlike, in structural form, well known types of curved nozzles found in the market, the only essential difference being in the application of the cut-off in the manner shown and hereinbefore described, the points of especial utility lying in its adaptability for use without kinking the tube and of accessibility of the cut-off.

Referring now to Fig. 2 it will be noticed that in this view the complete syringe and all of its parts are assembled within the cup C, the tube being coiled, as shown, and the nozzle and connector located above the latter and all of said parts securely held in place within such cup by the lid or cover L.

The operation is as follows: Referring first to Fig. l, the vessel A, shown as a basin, is filled with water and the cut-off is opened. Thev weight C which should be sufficient to prevent the withdrawal of the short leg or end, when the tube is filled with water, is lowered into the basin and the tube is slowly coiled -as immersed therein so as to permit the removal of all'of the air and the replacement thereof with water. The cutoff is then closed and the tube drawn out and downward quickly, under which conditions the water will be siphoned in a manner well understood, so that the instrument is ready for use in the same manner as an ordinary bag vfountain syringe, it being understood, of course, that the vvessel should be placed upon a mantel-piece or hung at such point as will give the desired pressure.

`In the application of my improved syringe I prefer to use a flexible rubber tube B of approximately one-half inch interior diameter and of sufficient rigidity to withstand any possibility of the tube becoming distorted where it passes over the edge of the basin A, as I find that with such a tube, even at the relatively low height of 29j ft., such as is the height of the bottom of stationary wash-basins, most excellent results can be had, by reason of the use of the flow of such a relatively large volume, the tube being preferably from 3 to l ft. in length.

I am aware that weights have heretofore been usedl with the induction ends of siphon tubes for siphoning liquids from barrels, casks and the like, and also that a siphon the same, such as are generally practised in the art of siphoning liquids.

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States is 1. A fountain syringe embracing a flexible tube, a nozzle therefor, and a cup provided withv a hollow neck in its bottom adapted to be secured to one end of the tube, said cup having sufficient containing capacity to hold thatend of the tube to which it is attached within a basin or other volume of water,

and also to inclose t-he tube and nozzle when not in use, substantially as described.

2. A fountain syringe embracing a flexible tube, a nozzle therefor, and a cup provided with a hollow neck in its bottom adapted to be secured to one end of the tube, said cup having sufficient containing capacity to hold that end of the tube to which it is attached within a basin or other volume of water; together with a cap for inclosing said parts, substantially as described.

3. A syringe nozzle of curvilinear form, having a neck for attaching it directly to the syringe tube; in combination with an adjustable cut-off axially located in alinement l" with the neck, whereby the nozzle is adapted for convenient use without kinking the tube and the cut-oftl rendered conveniently acces sible to the user, substantially as described.

4. A syringe nozzle of curvilinear form,

having a neck for attaching it directly to a syringe tube; in combination with a screwe valve located in alinement with the neck, the arrangement being such that the curvilinear form of the nozzle makes it capable of use without danger of kinking the tube and with the cutoff of easy access, substantially as described.

In testimony whereof I have signed my 'name to this specification in the presence of two subscribing witnesses.

CHARLES J. KINTNER.
